UK's Former AI Strategy Chief Joins Anthropic in Senior Role
Matt Clifford, the tech investor who shaped Britain's artificial intelligence policy under two prime ministers, has taken a senior position at the US company behind the Claude AI assistant.

Key points
- Matt Clifford, who drafted the UK government's AI action plan, has joined Anthropic, the US AI startup behind the Claude chatbot.
- Clifford was appointed AI opportunities adviser by Prime Minister Keir Starmer and previously advised Rishi Sunak on AI policy.
- He resigned from the unpaid government advisory role roughly six months into the post, citing personal reasons.
- Anthropic, founded in 2021, builds large language models, the technology that powers conversational AI tools like Claude and ChatGPT.
Matt Clifford built the UK's blueprint for competing in artificial intelligence. Now he is working for one of the American companies that blueprint was designed to attract.
As first reported by The Guardian, Clifford has accepted a senior role at Anthropic, the San Francisco startup that makes Claude, a large language model (a type of AI that reads and generates human language, the same underlying technology behind ChatGPT). The move comes roughly a year after he stepped back from advising 10 Downing Street.
Who is Matt Clifford?
Clifford is a well-regarded British tech investor and co-founder of Entrepreneur First, a company that helps researchers and engineers start deep-technology businesses. Keir Starmer appointed him as the government's AI opportunities adviser in 2024, following similar advisory work he had done for Rishi Sunak.
In that role, Clifford drafted the UK's AI Opportunities Action Plan, a government document designed to attract AI investment and set out a national strategy for the technology. He resigned from the unpaid post after about six months, citing personal reasons.
What does this mean for UK AI policy?
Clifford's departure from government was already a settled fact before this hiring. His move to Anthropic raises a question many observers will ask: does the man who wrote the rules end up helping a foreign company benefit from them?
That tension is not new. Senior policy advisers routinely move into industry roles, and Clifford held no regulatory or enforcement power. Still, the hire signals how intensely American AI companies are competing to recruit people with deep government relationships in major economies.
For ordinary people in Britain, the immediate practical effect is limited. Clifford's action plan remains government policy regardless of where he works next. What the move does show is how few senior AI policy experts exist worldwide, and how aggressively well-funded startups will recruit them.
Anthropichas raised tens of billions of dollars from investors including Google and Amazon and is considered one of a handful of labs at the very front of AI research globally, alongside OpenAI and Google DeepMind.
What happens next?
Anthropichas not yet detailed what Clifford's specific role will involve. Given his background, work involving government relations, public policy, or international expansion seems likely.
For anyone following UK AI policy, the near-term question is whether the government moves quickly to fill the gap in senior AI advisory capacity, or whether the revolving door between Whitehall and the tech industry becomes a pattern worth watching.
Common questions
Is Matt Clifford still involved in UK government AI policy?
No. He resigned from his unpaid adviser role roughly six months after his appointment and has now taken a private-sector position at Anthropic.
What does Anthropic actually make?
Anthropicbuilds Claude, an AI assistant that can answer questions, summarise documents, write text and carry out other language tasks. It is a direct competitor to OpenAI's ChatGPT.
